An orderly-micro-grooved PCD grinding wheel comprises a wheel hub, a polycrystalline diamond (PCD) film, several micro-grinding units, and several microgrooves. The PCD film is deposited on the outer circumferential surface of the wheel hub. The PCD film is processed using a water-jet guided laser device to form microgrooves with a high depth-to-width ratio and micro-grinding units with positive rake angles on the entire outer circumferential surface of the PCD film. The axial lengths of each micro-grinding unit and each microgroove are equal to the thickness of the grinding wheel, respectively. The microgrooves are spaced apart by the micro-grinding units.
